Subject: [PATCH V4 0/9] Add interconnect support to QSPI and QUP drivers
Date: Wed, 15 Apr 2020 15:53:09 +0530	[thread overview]
Message-ID: <1586946198-13912-1-git-send-email-akashast@codeaurora.org> (raw)

dt-binding patch for QUP drivers.
 - https://patchwork.kernel.org/patch/11436621/ [Convert QUP bindings
        to YAML and add ICC, pin swap doc]

High level design:
 - QUP wrapper/common driver.
   Vote for QUP core on behalf of earlycon from probe.
   Remove BW vote during earlycon exit call

 - SERIAL driver.
   Vote only for CPU/CORE path because driver is in FIFO mode only
   Vote/unvote from qcom_geni_serial_pm func.
   Bump up the CPU vote from set_termios call based on real time need

 - I2C driver.
   Vote for CORE/CPU/DDR path
   Vote/unvote from runtime resume/suspend callback
   As bus speed for I2C is fixed from probe itself no need for bump up.

 - SPI QUP driver.
   Vote only for CPU/CORE path because driver is in FIFO mode only
   Vote/unvote from runtime resume/suspend callback
   Bump up CPU vote based on real time need per transfer.

 - QSPI driver.
   Vote only for CPU path
   Vote/unvote from runtime resume/suspend callback
   Bump up CPU vote based on real time need per transfer.

Changes in V2:
 - Add devm_of_icc_get() API interconnect core.
 - Add ICC support to common driver to fix earlyconsole crash.

Changes in V3:
 - Define common ICC APIs in geni-se driver and use it across geni based
   I2C,SPI and UART driver.

Changes in V4:
 - Add a patch to ICC core to scale peak requirement
   as twice of average if it is not mentioned explicilty.
